network: only make progress when card reports new stuff happened

[zyuiop]

Fixes an old FIXME.

A very quick wrk benchmark on the axum example seems to report a 50% performance improvement (both tests were made with #1939 applied, the effect may be different without this patch).

Before:

$ wrk http://localhost:8080/ Running 10s test @ http://localhost:8080/ 2 threads and 10 connections Thread Stats Avg Stdev Max +/- Stdev Latency 19.91ms 58.94ms 716.76ms 92.84% Req/Sec 1.10k 342.95 2.09k 72.50% 21844 requests in 10.00s, 3.37MB read Requests/sec: 2184.33 Transfer/sec: 345.57KB 

After:

$ wrk http://localhost:8080/ Running 10s test @ http://localhost:8080/ 2 threads and 10 connections Thread Stats Avg Stdev Max +/- Stdev Latency 12.06ms 50.31ms 782.84ms 95.71% Req/Sec 1.69k 475.75 3.68k 79.00% 33619 requests in 10.00s, 5.19MB read Requests/sec: 3361.60 Transfer/sec: 531.81KB

This does not seem to work in all cases

edit: actually maybe it does, but then it requires the no-pre-emptive thing
